摘要：
Stable, agglomerate-free, low-viscosity graft copolymer dispersions are prepared by the radical polymerization of 25 to 65% by weight of ethylenically unsaturated monomers in the presence of a base polyol, a macromer, a low-molecular weight regulator and, optionally, an organic solvent. The dispersions of this process are suitable as a polyol component for the production of polyurethane plastics by the isocyanate addition process.
